What is the formula for calculating standard weight for children?

After the baby is born, every parent hopes that their child is safe and healthy. No matter it is a boy or a girl, they all hope that their child will grow tall. In fact, the standards for height and weight of babies are different at different stages. If you know the calculation formula for the baby's weight and height, you can directly grasp whether the child's growth is healthy.

Children's height and weight standard calculation formula

1. Standard weight measurement formula: Weight (kg) at 1 to 6 months = birth weight (or 3 kg) + age in months × 0.6 (kg); Weight (kg) at 7 to 12 months = birth weight (or 3 kg) + age in months × 0.5 (kg); Weight (kg) at 2 to 10 years old = age × 2 + 7 (or 8).

2. Standard growth pattern of height: The average height of a full-term baby is 50 cm. It increases by about 25 cm in the first year after birth, so it is about 75 cm at one year old. Thereafter, it increases by an average of about 5 cm each year. Therefore, the height (cm) of a child aged 2 to 12 years old = age × 5 + 75 (cm). Anyone whose height exceeds the standard by 10% or is less than 10% is considered abnormal.

3. Standard calculation formula for head circumference: The size of the head circumference is closely related to brain development. Head circumference measurement can be used as one of the indicators of children's intellectual development. The calculation formula is: head circumference = body length (cm) × 4/10 + 15.

Factors that affect your baby's height

1. Nutrition

Whether the baby's height is normal depends mainly on whether the bones grow normally, among which the development of the baby's skull, long bones of the limbs and spine is the most important. To ensure normal development of height, the baby's nutrition must keep up. Eat more foods that help grow taller and supplement more nutrients that are beneficial to normal bone growth, such as calcium, zinc, iodine, phosphorus, vitamin D and various proteins.

2. Sleep

If a child's body has less growth hormone, it will inevitably affect the normal development of the body, causing him to be short and thin.

Therefore, growth hormone plays a big role in the baby's height. When the baby goes to bed, the release of growth hormone is more obvious, which is beneficial to promote the growth of body tissues. Therefore, it is necessary to ensure the baby's sleep time and sleep quality so that the baby can be healthy and develop normally.

3. Exercise

Exercise is a positive and effective factor in the baby's growth. It is not only beneficial to the baby's height, but also helpful for improving physical fitness. Therefore, parents should consciously let their babies exercise their whole body to stretch their muscles and bones, promote blood circulation, and let their babies learn simple daily exercises such as lying prone, turning over, crawling, standing, and walking. As the baby gets older, running, jumping and other exercises can be increased appropriately. Do not let the baby sit for a long time or hold him in your arms for a long time. It seems to eliminate all dangers that the baby may encounter, but it affects the baby's physical health and normal development.

4. Disease

Diseases in infancy and childhood can have a huge impact on a child's life. Malnutrition makes the baby weak and sickly, while growth retardation makes the child suffer from the worry of not growing tall. If the baby is shorter than his peers for a long time, parents should pay attention to it and go to the hospital to seek medical help in time.

5. Genetics and Gender

In terms of genetics, the height of the parents will affect the height of the child. In terms of gender, it is a common phenomenon that girls are petite and boys are tall.

6. Living environment, social culture, climate region

A superior living environment and a high social and cultural level can allow babies to get good nutrition and treat diseases in a timely manner, thus growing taller. The geographical environment and climate region are also major factors that affect the baby's height. In my country, the weather in the north is cold and the animal husbandry is developed, so the growth environment is relatively better. Therefore, infants and young children in the north are significantly taller than those in the south.
